Cool project someone built with Pion WebRTC! Just saw this email and wanted to share. It seems like most telecommunications software just grows forever, so interested to see more focused solutions. ----- Dear colleagues, A friend of mine just did a three-hour first-year lecture over my unnamed SFU with 12 students. The students didn't switch on their camera (except during the break), the lecturer was streaming three flows: audio, video, and lecture slides. The total amount of network traffic oscillated between 4Mbps and 10Mbps (380kps to 800kbps for each receiver), which indicates that the congestion control algorithm is working as designed. The CPU load oscillated between 10% and 20% (of a $5/month VPS), which is more than in previous tests, I suspect that the CPU accounting of the VPS I'm renting is not accurate. Neither the lecturer nor the students (first years, non-STEM) had any problems with the software. One student reported problems with the video, which went away after a while. The students initially complained about the primitive UI (« au début, ça fait un peu peur »), then got used to it (« mais après, ça va »). I think the software is ready for a test at larger scale, say, a seminar with a hundred listeners or so. If anyone is organising a seminar and is willing to take the risk, please let me know.
